Intel Atom Z560

The Intel Atom Z560 is a Mobile-segment processor from Intel, built on the Atom architecture under the Silverthorne codename. The record lists a 45 nm process, 47 million transistors, a 26 mm² die, and a release date of May 31, 2010; it is marked End-of-life. The benchmark array is empty, avgBenchmarkScore is 0, percentileVsAllCpus is 50, and nearestRivals is empty, so this analysis is based on the specification fields and the relative fields that are actually present.

Benchmark Performance

No benchmark scores are recorded for the Z560. The benchmarks field is an empty array, and the avgBenchmarkScore field is 0. That zero is not an average of poor results; it is the average of no results. The nearestRivals field is also empty, meaning the database contains no rival names, no rival scores, and no deltaPct values for this processor. Consequently, no exact percentage comparison against neighboring CPUs can be made from this data. The only ranking-related number in the record is percentileVsAllCpus: 50. Interpreted literally, that is the median position in the database’s CPU distribution. However, nothing in the benchmark array supports that placement. With no scores and no rival list, the percentile should be read as a stored field rather than a measured outcome.

The spec-level execution resources are still clear. The part has one core, two threads, and a 2.13 base clock. The boost clock field is null, so no higher frequency appears in the data. The absence of benchmark data is itself the main result: the Z560 cannot be ranked with the same precision as processors that have populated benchmark arrays. The 50th percentile field is a position, but it is not anchored to any score in this record. The empty nearestRivals array also means there is no basis for a head-to-head percentage gap. In short, the benchmark portion of this record has no measured scores, no rival deltas, and a lone percentile value that cannot be verified from the rest of the data. Any performance conclusions must therefore come from the frequency, core, thread, cache, and power specifications, not from benchmark runs.

Power and Thermals

The power profile is dominated by a single value: the TDP field is 2. This is an extremely low thermal design power, and it implies a minimal cooling requirement. The record does not name a cooler, so no cooler size should be inferred; the thermal tier can only be described qualitatively. A part with TDP 2 sits in the light-duty cooling class, far below the thermal requirements of mainstream desktop processors, though the record does not state a specific cooling solution.

The silicon details are consistent with a low-power design. The process node is 45 nm, the die size is 26 mm², and the transistor count is 47 million. A 26 mm² die is physically small, and the small area limits the surface over which heat is generated. The foundry is Intel. The architecture is Atom, and the generation field is Atom (Silverthorne), a mobile-oriented generation. The market segment is Mobile. There is no boost clock, so the power envelope does not include a separate high-frequency burst state in the record; the only clock listed is 2.13. The TDP field is the only power specification present. No other thermal, current, or cooling data exists in the pack. Therefore, the cooling tier implied by the data is the tier matched to a chip with TDP 2 and a 26 mm² die: a light-duty mobile thermal solution. Whether that solution is passive or active is not stated.

Single-Thread vs Multi-Thread Behavior

The Z560 has one core and two threads. That topology defines its behavior more than any benchmark would. A single physical core means all execution must pass through the same core resources; the second thread provides a way to run two software threads on that core. The base clock is 2.13, and the boost clock is null. There is no second, higher frequency in the record for short single-thread bursts, so a single-threaded workload has a fixed 2.13 target. This is a serial-oriented configuration.

Cache sizes are reported per core: 56 KB of L1 and 512 KB of L2. Because the processor has exactly one core, the per-core figures are also the total figures for the chip: 56 KB of L1 and 512 KB of L2. The record lists no L3 cache; the l3 field is null, totalL3 is null, and vCache3d is also null. For single-thread workloads, the processor can use the full core and the full cache. For two-thread workloads, the processor has two thread slots but no second physical core. For workloads that need more than two threads or more than one physical core, the data shows no scaling path beyond the one core. The real-world split is therefore: single-thread tasks get one core at 2.13; multi-thread tasks get one core and two thread slots. The benchmark section does not provide a score to quantify that split, but the core and thread counts alone show that this is not a parallel-processing part. The L1 and L2 cache values are per-core and, with one core, they translate directly to total cache. The absence of a boost clock also means the single-thread versus multi-thread difference is not about turbo behavior; there is no boost field to create a frequency gap between lightly loaded and fully loaded states.

Who Should Consider It

The Z560 is a Mobile segment part and is marked End-of-life. Those two fields already frame the recommendation. The part is not in production, and the record contains no performance evidence for current software. The processor has one core, two threads, and a 2.13 base clock. No boost clock is listed. It has no integrated graphics on the processor itself; the integrated graphics field is “On certain motherboards (Chipset feature)”, so graphics capability depends on the motherboard chipset.

Gaming cannot be recommended from this data. There are no benchmark scores, and a one-core, two-thread processor with no on-chip GPU is a severe constraint for game workloads. Content creation that relies on multiple cores is likewise unsupported by any record. Office-type work that is serial and fits within one core is the only plausible workload profile from the specification data, but the only frequency is 2.13 and the design is a 45 nm mobile part. The multiplier is locked, so there is no overclocking path. The person who should consider this part is one assembling a legacy low-power mobile system that can use the chipset-mediated graphics path and that does not require more than one physical core or more than two threads. The record gives no score that would extend the recommendation beyond that narrow profile. It is an end-of-life mobile processor, and for workloads outside its specification constraints, the data contains no numbers to support a positive assessment.

Platform and Compatibility

The platform information is sparse but specific. The socket is Intel BGA 441. The architecture is Atom, the codename is Silverthorne, and the generation field is Atom (Silverthorne). The process node is 45 nm and the foundry is Intel. The part number is SLH63.

Memory details are almost entirely absent from the record. The memorySupport field is null, memoryBus is null, and memoryBandwidth is null. No memory type, channel configuration, or bandwidth figure can be confirmed. ECC memory is false, so the record explicitly does not support ECC. PCIe is null, meaning no PCIe generation or lane count is listed. L3 cache is null, and totalL3 is null. The multiplier is not unlocked. The integrated graphics field says “On certain motherboards (Chipset feature)”, which places graphics functionality on the chipset rather than in the CPU.

For upgrade path, the record is clear only in a negative way. The production status is End-of-life. The release date is May 31, 2010. The nearestRivals list is empty, and the series field is null, so there is no named successor or sibling part to point to. Because the package is Intel BGA 441, the data does not describe a socketed upgrade process. The only compatible platform details are the socket, architecture, process node, and chipset-mediated graphics; memory and PCIe compatibility are undocumented. An integrator cannot infer memory support from this record, and ECC is explicitly unsupported. The platform story is therefore: Intel BGA 441, Atom Silverthorne generation, 45 nm Intel process, chipset-dependent graphics, locked multiplier, no memory details, no PCIe details, and end-of-life status.
